The short answer
The Odds bet is the only wager in the casino paid at True Mathematical Odds, resulting in a 0% house edge.
The full calculation
True odds are calculated by the ratio of ways to roll the Point number versus the ways to roll a 7.
- Points 4 and 10: 3 ways to roll vs 6 ways to roll a 7. True Odds: 2 to 1.
- Points 5 and 9: 4 ways to roll vs 6 ways to roll a 7. True Odds: 3 to 2.
- Points 6 and 8: 5 ways to roll vs 6 ways to roll a 7. True Odds: 6 to 5.
If you bet $10 in odds on a point of 4, and the 4 hits, you are paid exactly $20. There is no house “cut.” This is why taking the maximum allowed odds is the most effective way to minimize your total session house edge.
What this means at the table
By taking full “3x-4x-5x” odds on a $10 Pass Line bet, your total money in action across a two-hour session (averaging 30 resolved points) is roughly $1,150. However, your theoretical loss remains identical to if you had bet only the Pass Line with no odds—roughly $4.23 for the entire session. You are essentially getting 3.5 times the “gamble” for the same mathematical price.
Common mistakes around this number
Players often mess up the “Even/Odd” math. Because the 5 and 9 pay 3:2, you should always place your odds in an even amount (e.g., $10 wins $15). If you bet $5 on odds for the 5, the casino cannot pay you $7.50, so they will pay you $7 and keep the 50 cents. This “breakage” creates a hidden house edge on a bet that should be 0%. Always bet an even amount on the 5 and 9 odds.

In Detail
A craps odds chart is not decoration. It is the table’s price list, and once you can read it, half the mystery loses its costume.
This page is about reading probability, true odds, payouts, and house edge from a chart. On the surface, that may sound like one small corner of craps, but in a real casino it touches the three things that decide whether a player survives the table: the written rule, the payout, and the way the bet feels when chips are already in action. Craps is dangerous for beginners because a bet can feel smart, social, or lucky while still being badly priced.
The math that matters: Two dice create 36 equally likely ordered combinations. The shape of the game comes from that grid: 7 has 6 combinations, 6 and 8 have 5 each, 5 and 9 have 4 each, 4 and 10 have 3 each, 3 and 11 have 2 each, and 2 and 12 have only 1 each. Point odds come from comparing the point to the 7: 4/10 are 3 vs 6, so 2:1; 5/9 are 4 vs 6, so 3:2; 6/8 are 5 vs 6, so 6:5. Expected value is the grown-up way to price a bet: $EV=\sum(P_i\times W_i)-\sum(P_j\times L_j)$. If the payout is smaller than the true probability deserves, the difference is the house edge.
What it means on the felt: Charts reveal the haircut between true odds and casino payouts. That haircut is where the house earns. A player who understands this subject does not need to act like a robot. You can still enjoy the noise, the shooter, the stick calls, and the little rush when the dice leave the hand. The point is to know when you are paying for entertainment and when you are making a lower-cost decision.
Casino-floor truth: Craps is built to move. The table crew wants clear bets, fast decisions, and clean payouts. The layout also nudges attention toward action. The safest-looking move is not always the cheapest move, and the loudest bet is almost never the best one. Good craps play is not about predicting the next roll. It is about refusing to overpay for it.
The mistake to avoid: Do not read a payout chart like every box is equal. It is a price list, not a wish list. Also, never judge this topic by one lucky hit or one ugly loss. Short sessions are noisy. The math only shows its face over repeated decisions, which is exactly why casinos are patient and players are usually not.
